oscat.lib fuer TwinCAT/CoDeSys / declare variables

« am: 20. Februar 2011, 19:50:50 »

i would like to opt for declare variables for some as i see a lot of 0.0 and 1.0 in the lib.
o would like to put them as
zero : real:=0.0;
one : real:=1.0;
hundred :real:=100.0;
etc

inside a function declare them, this to avoid calc errors with int and real all over the place.
or global

the place where is a discussion i would like to have here.
so just vote for local inside a function or function block or global.
